I don’t like to do that but can’t find the dimensions.
I would like to have the hole pattern dimension of the screw since i have ordered them for my Gimbal.
The four threaded holes are located on a 0.625" diameter circle and are 4-40. The outer diameter should be 0.870", and the set screw is 10-32. The inner “lip” is 0.370" diameter. The bore diameter varies by hub number (4mm, 6mm, 1/4" etc).
